is it necessary to use both usb connections or will one suffice?

Yes, one is for data and the other is for power. Sometimes a USB port won't supply enough power through one port. I have used an adapter that just had one USB. This one does require the use of both.

One was sufficient for my hard drive. I imagine it depends on the power needs of the drive.

I only use 1 connector. It depends on the PC your using, some computers have low USB current, they require to connectors.

I installed using only one usb connecter. Just as a precaution (to make sure that my computer was putting out enough "juice") I made sure my computer was plugged into the wall. I had no problem with the transfer. Good luck.

I've heard the reason for the two USB's is in case you have a computer that doesn't provide enough power on just one USB, then you have to use two. It seems to work fine with just one USB with my Compaq (HP) 6730s laptop. I've also tried in on my HP desktop and it also works with just one USB. My thoughts are, try it with one and if it works, great! If not, then you'll have to use two.

No it's not possible paring more than one at the same time, you should discconect the current device if you want to connect a different device.

You need to plug both in because one transfers data and the other supplies power. If you can only connect one then you need a usb splitter.

Yes, one is for data, the other is for power. Though it may be possible to use a USB charger for this connection. I have used the unit with a tablet by using a multi-port adapter.

As far as i can tell yes. I have only used the usb connection a couple times however.

No it does not (in most instances). I have always used it with just a single USB connection.

Yes. Although if you want to use both at the same time, you'll need an adapter

Hi Joel, Sorry I have no idea if you can connect and operate more than one. If there is a way to select which USB port the software is connecting to then it might be possible.It is a good question. I am curious why do you want to connect more than one?Regards,Chris Schene

No, one cable is for data, one only provides power. It will work at the same speed as any other usb cable.

yes it is required 2 usb 2.0 port, but actually I am using with just one usb 3.0, and for it working very good and I am using very big software like Inventor or ANSys.

It has 2 separate connectors for USB 2.0/3.0 and separate ports, so it would be simultaneous. Don't buy this though, its junk, it stopped working and now is a $30 spacer in my desktop.

No. Just two USB ports. One for power & data and another just for additional power.

Ok it has 2 usb plugs that need to be plugged in at the same time? If this is so will having a usb hub running usb3 work (my hub has the duo like plug side by side on one plug)

I think you can link two of them together. Not sure about the USB and estata connections.

Yes, you need to use 2 usb ports for the extra power. The supplied usb Y cable has about 5 inches of slack between the plugs. If your laptop only has 1 usb on each side you will have to get an extension.

I have used the USB and SD card reader at the same time without problem. Hope it works for you as well.
